Hey, great. Finally you made it, Loopy. Thanks that you spent so much work on it.
Well, the effect looks a little different from what the website picture shows. Wont start a discussion again. But I think, the pane just stands under a different pressure than the others, for what reason ever. It gets deformed a little by that and so the light will be reflected in a different way. Its just my guess, cause I'm no building expert.
